Dear Peter:

         1. General. Golden Star Resources Ltd., a Canadian corporation (the
"COMPANY"), plans to make a take-over bid in Canada and concurrent tender offer
in the United States (the "OFFER") for all of the outstanding common shares (the
"SECURITIES") of IAMGold Corporation ("IAMGOLD") for consideration consisting of
1.15 common shares of the Company (the "COMPANY SHARES") for each Security, on
the terms and subject to the conditions set forth in the Offer to Purchase and
Circular filed with the Ontario Securities Commission (the "OSC") on the date
hereof and attached hereto as Exhibit A (as amended, the "OFFER TO PURCHASE"),
the Preliminary Prospectus dated June 9, 2004 and attached hereto as Exhibit B
(and as amended or supplemented from time to time prior to effectiveness of the
Registration Statement (as defined below), the "PRELIMINARY PROSPECTUS"), and
the related Letter of Acceptance and Transmittal (the "LETTER OF TRANSMITTAL")
dated June 9, 2004 and attached hereto as Exhibit C. The Company also intends to
solicit proxies from IAMGold shareholders to vote against the proposed
arrangement between IAMGold and Wheaton River Minerals Ltd. (the "Proxy
Solicitation"). The schedules attached to this Agreement shall, for all purposes
of this Agreement, form an integral part of it.

         The following materials to be used by the Company in connection with
the Offer, as any of them may be amended, modified or supplemented from time to
time, are collectively referred to herein as the "OFFER MATERIAL":

                  (a) The Offer to Purchase;

                  (b) The Company's Registration Statement on Form S-4 filed
         with the Securities and Exchange Commission (the "COMMISSION") on June
         10, 2004, in accordance with the Securities Act of 1933, as amended,
         and the rules and regulations of the Commission thereunder
         (collectively, the "1933 ACT") relating to the Offer and the issuance
         of the Company Shares in connection therewith. As used in this
         agreement (the "DEALER MANAGER AGREEMENT" or this "AGREEMENT"), the

         becomes effective under the 1933 Act, and as amended or supplemented

         the effectiveness of the Registration Statement, the prospectus, if
         any, filed with the Commission pursuant to Rule 424(b) under the 1933
         Act, in the form it was first filed, provided that such prospectus was
         used to solicit tenders of Securities to the Offer on or prior to the

         incorporated, or deemed to be incorporated, by reference (such
         incorporated documents, financial statements and schedules being herein
         called the "INCORPORATED DOCUMENTS"). For purposes of this Agreement,
         all references to the Registration Statement, any preliminary

         Transmittal.

                  (e) Any other documents or materials whatsoever (including
         newspaper announcements and press releases) relating to the Offer that
         are distributed or made available to the public or the holders of the
         Securities by or at the direction of the Company in connection with the
         Offer.

         2. Engagement as Dealer Manager and Dissident Proxy Solicitor.. (a) The
Company hereby retains BMO Nesbitt Burns, Inc. in Canada, and Harris Nesbitt
Corp., in the United States, to (i) act as the dealer manager with respect to
the Offer (together, the "DEALER MANAGER") and to form and manage a group
(together with the Dealer Manager, the "SOLICITING DEALER GROUP") consisting of
members of the Investment Dealers Association of Canada and the Toronto Stock
Exchange, or of the National Association of Securities Dealers, to act as


                                      -2-
<PAGE>


soliciting dealers with respect to the Offer (each a "SOLICITING DEALER") and
(ii) assist the Company with the Proxy Solicitation (together, the "Dissident
Proxy Solicitor"). On the basis of the representations and warranties and
agreements of the Company herein contained and subject to and in accordance with
the terms and conditions hereof and of the Offer Material, you hereby agree to
act as Dealer Manager in connection with the Offer and Dissident Proxy Solicitor
in connection with the Proxy Solicitation and in connection therewith, you shall
act in accordance with your customary practices and shall perform those services
in connection with the Offer and Proxy Solicitation that are customarily
performed by investment banking firms in connection with acting as a dealer
manager of take-over bids or exchange offers of a like nature and a dissident
proxy solicitor, including, but not limited to, soliciting tenders pursuant to
the Offer and communicating generally regarding the Offer and Proxy Solicitation
with brokers, dealers, commercial banks and trust companies and other persons,
including the holders of the Securities. The Soliciting Dealers will, on behalf
of the Company, use their reasonable efforts to solicit shareholders of IAMGold
to tender their Securities to the Offer and vote their Securities in the Proxy
Solicitation and are hereby authorized by the Company to make favorable
recommendations as to the Offer and Proxy Solicitation, by publication or other
appropriate oral, electronic or written communication provided that each such
publication or communication is made in accordance with the applicable
securities legislation, regulations, rules, policy statements, rulings, orders
and published notices of the securities regulatory authorities in Canada and the
United States and the applicable rules, by-laws and policies of applicable stock
exchanges (collectively, the "SECURITIES LEGISLATION").

         (b) Neither the Dealer Manager nor any Soliciting Dealer will be
required to perform services except where lawfully licensed or registered to so
do, or pursuant to applicable exemptions from licensing and registration under
applicable law. Subject to the Securities Legislation, the Dealer Manager shall
be entitled to trade as agent for other parties, but not as principals, in the
securities of the Company and IAMGold and to otherwise advise its clients in
accordance with its duties to such clients.

         (c) The Dealer Manager agrees to conduct the solicitation and to
perform the other services hereunder in accordance with the Securities
Legislation and the terms hereof and to obtain the agreement of each Soliciting
Dealer to conduct the solicitation and perform its services in accordance with
the Securities Legislation; provided, however, that the Dealer Manager will not
be responsible for the actions of any other Soliciting Dealer, as each will be
responsible for its own actions.

         (d) The Dealer Manager agrees not to solicit or otherwise communicate
in respect of the Offer or Proxy Solicitation in any jurisdiction where, or from
any person in respect of which, the Offer is expressed to be excluded or not
made.

         (e) The Company acknowledges and agrees that the Dealer Manager has
been retained hereunder to act solely as Dealer Manager and Dissident Proxy
Solicitor. In such capacity, the Dealer Manager shall act hereunder as an
independent contractor and shall not be deemed the agent or fiduciary of the
Company or any of its affiliates, equity holders or creditors or of any other
person, and any of the duties of the Dealer Manager arising out of the Dealer
Manager's engagement pursuant to this Agreement shall be owed solely to the
Company. None of the Soliciting Dealers (including the Dealer Manager) shall be
liable to the Company, its


                                      -3-
<PAGE>


affiliates, equity holders or creditors or to any other person for any act or
omission on the part of, and shall not be deemed to be the agent or fiduciary
of, any broker or dealer, commercial bank or trust company other than such
Soliciting Dealer and no such broker or dealer, commercial bank or trust company
shall be deemed to be acting as the agent or fiduciary any of the Soliciting
Dealers. Nothing contained in this Agreement shall constitute any of the
Soliciting Dealers (including the Dealer Manager) a partner of or joint venturer
with the Company.

         (f) The Dealer Manager shall not be subject to any loss, claim, damage,
liability or expense owed to the Company or any of the Company's affiliates or
subsidiaries for any act or omission on the part of any broker or dealer in
securities (other than the Dealer Manager), bank, trust company, nominee or any
other person, and the Dealer Manager shall not be liable for (i) its own acts or
omissions in performing its obligations as Dealer Manager or Dissident Proxy
Solicitor, or (ii) for any loss, claim, damage, liability or expense incurred by
any person in connection with the Dealer Manager performing its obligations as
Dealer Manager or Dissident Proxy Solicitor hereunder, except for any losses,
claims, damages, liabilities and expenses determined in a final judgment by a
court of competent jurisdiction to have resulted directly from any such acts or
omissions undertaken or omitted to be taken by the Dealer Manager through its
negligence or willful misconduct. In soliciting or obtaining tenders of
Securities or votes in the Proxy Solicitation, the Company hereby acknowledges
that the Dealer Manager is and will be acting as an independent contractor and
shall not be deemed to be acting as the agent of the Company or as the agent of
any broker, dealer, bank, trust company, nominee or other person and no broker,
dealer, bank, trust company, nominee or other person shall be deemed to be
acting as the agent of the Dealer Manager or any of its subsidiaries or
affiliates.

         3. Solicitation Material, Withdrawal. The Company agrees to furnish
each Soliciting Dealer with as many copies as you may reasonably request of any
Offer Material. The Company will, in a timely manner, provide the Dealer Manager
with a duplicate list of the names and addresses of the registered shareholders
of IAMGold and The Canadian Depository for Securities Limited participant list,
in such form(s) as are in the possession of the Company. The Company agrees
that, within a reasonable time prior to using any Offer Material, it will submit
copies of such material to you and will not use or publish any such material
without your comment. During the term of the Offer and so long as the
Registration Statement shall be effective, the Company shall inform you promptly
after it receives notice or becomes aware of the happening of any event, or the
discovery of any fact, that would require the making of any change in any Offer
Material then being used or that would affect the accuracy or completeness of
any representation or warranty contained in this Agreement if such
representation or warranty were being made immediately after the happening of
such event or the discovery of such fact.

         In the event that (i) the Company uses or permits the use of any Offer
Material (a) that has not been submitted to you and your counsel for comment, or
(b) that has been so submitted and with respect to which you or your counsel
have made comments, but which comments have not resulted in a response
reasonably satisfactory to you to reflect such comments, (ii) the Company shall
have breached any of its representations, warranties, agreements, obligations or
covenants contained herein, (iii) there shall have occurred any material adverse
change in the business or operations of the Company and its subsidiaries taken
as a whole (a "MATERIAL ADVERSE EFFECT"), that, in your judgment, makes it
impracticable or inadvisable to carry out the Offer, the exchange of Securities
pursuant thereto or the performance of this Agreement, (iv) the



                                      -4-
<PAGE>


Offer is terminated or withdrawn for any reason or (v) any stop order,
restraining order, injunction or denial of an application for approval has been
issued in connection with the Offer and not thereafter stayed or vacated or any
proceeding, litigation or investigation in connection with the Offer has been
initiated, that, in either case in your judgment, makes it impracticable or
inadvisable to carry out the Offer, the exchange of Securities pursuant thereto
or the performance of this Agreement, then in any such case you shall be
entitled to withdraw as a Dealer Manager, by providing written notice of such
withdrawal to the Company, without any liability or penalty to you or any
Personnel (as defined in Schedule I hereto) and without loss of any right to the
payment of all expenses payable in accordance with Section 5 hereunder which
have been incurred by you to the date of such withdrawal. If you withdraw as
Dealer Manager in accordance with the foregoing provision, the reimbursement for
your expenses through the date of such withdrawal shall be paid to you promptly
after such date. Notwithstanding anything contained in this Agreement to the
contrary, the Company may, in its discretion, carry out the Offer after your
withdrawal as Dealer Manager, provided that the Company (y) amends or
supplements the Offer Material to disclose that you have withdrawn as Dealer
Manager and (z) utilizes a means reasonably calculated to reach holders of the
Securities to inform them of such withdrawal.

         4. Compensation. The Company shall not pay the Dealer Manager any
additional professional fees for forming and managing the Soliciting Dealer
Group or for acting as the Dissident Proxy Solicitor.

         5. Expenses. The Company agrees to pay all of your reasonable
out-of-pocket costs and expenses (including legal fees and GST) incurred in
connection with your service as Dealer Manager and Dissident Proxy Solicitor.
The Company agrees that it will pay all of the following expenses related to the
Offer: (i) all fees and expenses relating to the preparation, printing, mailing
and publishing of the Offer Material, including the cost of preparation and
filing of the Registration Statement and any amendment thereto and Schedule
14D-1F and any Amendments thereto, (ii) all fees and expenses of the Company's
counsel and accountants and of the information agent, (iii) all advertising
charges, (iv) all fees and expenses of any depositary, transfer agent or other
person rendering services in connection with the Offer, (v) mailing and handling
expenses incurred by brokers and dealers (including you), commercial banks,
trust companies and other nominees in forwarding the Offer Material to their
customers, (vi) the cost of the preparation, issuance and delivery of the
Company Shares, including any and all transfer and other taxes payable thereon,
except as otherwise stated in the Letter of Transmittal, (vii) all expenses in
connection with the qualification of the Company Shares for offer and delivery,
(viii) all costs and expenses incident to the additional listing of the Company
Shares on the American Stock Exchange and the Toronto Stock Exchange and (ix)
all other costs and expenses (including taxes and GST) incident to the
performance of the obligations of the Company hereunder for which provision is
not otherwise made in this Section. All payments to be made by the Company to or
on behalf of the Dealer Manager pursuant to this Section 5 shall be made
promptly after the expiration or termination of the Offer or withdrawal by you
from acting as Dealer Manager in accordance with Section 3 or, if later,
promptly after the related fees or expenses accrue and are invoiced. The Company
shall perform its obligations set forth in this Section 5 whether or not the
Offer is commenced or the Company acquires any Securities pursuant to the Offer
or otherwise.



                                      -5-

         6. Depositary. The Company has appointed CIBC Mellon Trust Company (the
"DEPOSITARY") to act as its Depositary. The Company will instruct the Depositary
to provide, from time to time, designated employees of the Dealer Manager with
such timely information as the Dealer Manager may reasonably request as to the
number of Securities that have been tendered and received by the Depositary and
the names of holders of such Securities, including a list in writing (as soon as
practicable) of the names and addresses of the Soliciting Dealers whose names
have been designated in the appropriate space on the Letter of Transmittal
delivered to the Depositary or to the Company in accordance with the
instructions on the Letter of Transmittal enclosed with the Offer Material and
the number of Securities as to which each Soliciting Dealer was so designated.

         7. Representations, Warranties and Certain Agreements of the Company.
The Company represents and warrants to the Dealer Manager, and agrees with the
Dealer Manager, as of the date hereof, as of the date of commencement of the
Offer (the "COMMENCEMENT DATE") and as of the date on which the Securities are
accepted by the Company pursuant to the Offer (the "ACCEPTANCE Date") (unless
another date is specifically referenced in which case the representation and
warranty shall speak as of such date) as set forth on Schedule II provided,
however, that, if the representations and warranties set forth on Schedule II
are not true and correct as of the Acceptance Date, the Dealer Manager may
withdraw as Dealer Manager in accordance with the second paragraph of Section 3.

         8. Additional Agreements. (a) The Company shall notify you immediately
and, if requested, shall notify you in writing of (i) when the Registration
Statement has become effective and when any Prospectus is mailed (or otherwise
sent) for filing pursuant to Rule 424 under the 1933 Act, (ii) the receipt of
any comments from the Commission or the OSC, (iii) any request by the Commission

suspending the effectiveness of the Registration Statement or any post-effective
amendment thereto or of any order preventing or suspending the use of the
Preliminary Prospectus or any Offer Material, or of the suspension of the
qualification of the Securities for offering or sale in any jurisdiction, or of
the initiation or threatening of any proceedings for any of such purposes, (vi)
the occurrence of any event that could cause the Company to withdraw or
terminate the Offer or would permit the Company to exercise any right not to
accept tendered Securities, (vii) any proposal or requirement to make, amend or
supplement any other Offer Material, (viii) the commencement of any material
litigation or the issuance of any order or the taking of any other action by any
administrative or judicial tribunal or other governmental agency or
instrumentality concerning the Offer (and, if in writing, will furnish you a
copy thereof), (ix) the issuance by any provincial or state securities
commission or other regulatory authority of any order suspending the
qualification or the exemption from qualification of the Company Shares under
state securities or blue sky laws or the initiation or threatening of any
proceeding for that purpose, (x) the occurrence of any event, or the discovery
of any fact, the occurrence or existence of which would reasonably be expected
to (a) cause the Company to amend, withdraw or terminate the Offer, (b) cause
any representation or warranty contained in this Agreement to be untrue or
inaccurate, or (c) permit the Company to exercise any right not to exchange the
Securities tendered under the Offer (and


                                      -6-
<PAGE>


the Company will so advise you before such rights are exercised) and (xi) any
other information relating to the Offer which you may from time to time
reasonably request.

         The Company agrees that if any event occurs or condition exists as a
result of which the Offer Material would include an untrue statement of a
material fact, or omit to state any material fact necessary to make the
statements therein, in light of the circumstances existing when the Offer
Material is delivered to a holder of Securities, not misleading, or if, in the
opinion of the Company, after consultation with you, it is necessary at any time
to amend or supplement the Offer Material to comply with applicable law, the
Company shall immediately notify you, prepare an amendment or supplement to the
Offer Material that will correct such statement or omission or effect such
compliance and supply such amended or supplemented Offer Material to you.

         (b) The Company will promptly effect the filings necessary pursuant to
Rule 424 and will take such steps as it deems necessary to ascertain promptly
whether the Prospectus transmitted for filing under Rule 424 was received for
filing by the Commission and, in the event that it was not, it will promptly
file the Prospectus. The Company will make every reasonable effort to prevent
the issuance of any stop order and, if any stop order is issued, will make every
reasonable effort to obtain the lifting thereof at the earliest possible moment.

         The Company will file promptly all reports or information statements
required to be filed with the Commission pursuant to Section 13(a), 13(c), 14 or
15(d) of the 1934 Act subsequent to the date of the Preliminary Prospectus and
for so long as the delivery of a prospectus is required in connection with the
Offer. The Company will promptly file with the Commission on the Commencement
Date a Schedule 14D1-F and will promptly file as required any and all necessary
Amendments.

         (c) On the Commencement Date, the Company will cause to be delivered to
each registered holder of the Securities, as soon practicable, a copy of the
Preliminary Prospectus and Letter of Transmittal and all other appropriate Offer
Material. Thereafter, to the extent practicable until the expiration or
termination of the Offer, the Company will use all reasonable efforts to cause
copies of such material to be mailed to each person who becomes a registered
holder of any Company Shares.

         (d) The Company will give you notice of its intention to file or
prepare any amendment to the Registration Statement (including any filing under
Rule 462(b) of the 1933 Act regulations), or any amendment, supplement or
revision to either the prospectus included in the Registration Statement at the
time it became effective or to the Prospectus, whether pursuant to the 1933 Act,
the 1934 Act or otherwise, will furnish you with copies of any such documents a
reasonable amount of time prior to such proposed filing or use, as the case may
be, and will not file or use any such document to which you shall reasonably
object, but nothing herein shall prevent the Company from complying with
applicable law.

         (e) The Company has furnished or will deliver to you, without charge,
one signed copy of the Registration Statement as originally filed and of each
amendment thereto (including exhibits filed therewith or incorporated by
reference therein and documents incorporated or deemed to be incorporated by
reference therein) and signed copies of all consents and certificates


                                      -7-
<PAGE>


of experts, and will also deliver to you, without charge, as many conformed
copies of the Registration Statement as originally filed and of each amendment
thereto (without exhibits) as you may reasonably request. The Company further
agrees that the Registration Statement and each amendment thereto furnished to
you will be identical to any electronically transmitted copies thereof filed
with the Commission pursuant to EDGAR, except to the extent permitted by
Regulation S-T.

         (f) The Company will deliver to you, without charge, as many copies of
the Prospectus and the other Offer Materials as you may reasonably request, and
the Company hereby consents to the use of such copies for purposes permitted by
the 1933 Act and as contemplated hereunder. The Company will furnish to you,
without charge, during the period when the Prospectus is required to be
delivered under the 1933 Act or the 1934 Act, such number of copies of the
Prospectus and the other Offer Materials as you may reasonably request. The
Company further agrees that the Prospectus and the other Offer Materials and any
amendments or supplements thereto furnished to you will be identical to any
electronically transmitted copies thereof filed with the Commission pursuant to
EDGAR, except to the extent permitted by Regulation S-T.

         (g) The Company will comply with the 1933 Act and the 1934 Act so as to
permit the completion of the distribution of the Company Shares as contemplated
in this Agreement and in the Registration Statement and the Prospectus. If at
any time when the Prospectus is required by the 1933 Act or the 1934 Act to be
delivered in connection with the distribution of the Company Shares, any event
shall occur or condition shall exist as a result of which it is necessary, in
the opinion of counsel for the Company, to amend the Registration Statement in
order that the Registration Statement and the other Offer Materials will not
contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading or to amend or supplement the Prospectus in order that the Prospectus
will not include an untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein not misleading
in the light of the circumstances existing at the time it is delivered to a
holder of Securities, or if it shall be necessary, in the opinion of such
counsel, at any such time to amend the Registration Statement or amend or
supplement the Prospectus in order to comply with the requirements of the 1933
Act, the Company will promptly prepare and file with the Commission, subject to
the terms of this Agreement, such amendment or supplement as may be necessary to
correct such statement or omission or to make the Registration Statement or the
Prospectus comply with such requirements, and the Company will furnish to you,
without charge, such number of copies of such amendment or supplement as you may
reasonably request.

         (h) The Company will use all reasonable efforts to qualify the Company
Shares for offering and sale under the applicable securities laws of such states
of the United States and in such provinces of Canada as you and the Company may
reasonably designate; provided, however, that the Company shall not be obligated
to file any general consent to service of process or to qualify as a foreign
corporation or as a dealer in securities in any jurisdiction in which it is not
so qualified or to subject itself to taxation in respect of doing business in
any jurisdiction in which it is not otherwise so subject.


                                      -8-

         (i) The Company will not, directly or indirectly, distribute the Offer
Material to any holder of Securities in or from any jurisdiction outside the
United States or Canada, or otherwise extend the Offer to any holder of

circumstances that will result in compliance with the applicable laws and
regulations of such jurisdiction.

         9. Documentary Covenants. (a) The Company covenants that it shall,
within three business days of the Commencement Date, deliver or cause to be
delivered to you each of (i) the signed opinion, dated within three business

operations of the Company and its subsidiaries taken as a whole (other than as
set forth in the Prospectus).

         (b) Unless you have previously withdrawn as Dealer Manager, the Company
covenants that it shall, on the Acceptance Date, deliver or cause to be
delivered to you each of the documents listed in clauses (i) through (v) below
and that it will not accept Securities tendered pursuant to the Offer unless on

in accordance with Schedule I, attached hereto which schedule forms a part of
this Agreement and the consideration for which is the entering into of this
Agreement. Such indemnity shall be in addition to, and not in substitution for,
any liability at law, in equity or otherwise, which the Company or any other
party may have to the Dealer Manager or to the other parties to such indemnity.

or public policy, all other provisions of this Agreement shall nevertheless

the agreements contained herein is not affected in any manner adverse to any
party. Upon such determination that any term or provision is invalid, illegal or

indemnity or contribution hereunder, shall inure to the benefit of and be
binding upon the Company, the Dealer Manager, NBI (as defined in Schedule I),

to any other person or entity any right hereunder or by virtue hereof.

                                   SCHEDULE I

GOLDEN STAR RESOURCES LTD. (the "Indemnitor") hereby agrees to indemnify and
hold BMO Nesbitt Burns Inc., Harris Nesbitt Corp. and/or any of their respective
subsidiary or affiliated companies (hereinafter collectively referred to as
"NBI") and each and every of the directors, officers, employees, agents and
shareholders of NBI (hereinafter referred to as the "Personnel") harmless from
and against any and all expenses, losses, claims, actions, damages or
liabilities, joint or several (including the aggregate amount paid in reasonable
settlement of any actions, suits, proceedings or claims and the reasonable fees
and expenses of its counsel that may be incurred in advising with respect to
and/or defending any claim that may be made against NBI) to which NBI and/or its
Personnel may become subject or otherwise involved in any capacity under any
statute or common law or otherwise insofar as such expenses, losses, claims,
damages, liabilities or actions arise out of or are based, directly or
indirectly, upon the performance of professional services by NBI or its
Personnel in connection with the matters referred to in the attached letter
agreement, provided, however, that this indemnity shall not apply to the extent
that a court of competent jurisdiction in a final judgment that has become
non-appealable shall determine that:

(i)    NBI or its Personnel have been negligent or dishonest or have committed
       any fraudulent act in the course of such performance; and

(ii)   the expenses, losses, claims, damages or liabilities, as to which
       indemnification is claimed, were directly caused by the negligence,
       dishonesty or fraud referred to in (i).


If in connection with any legal proceeding, for any reason (other than the
occurrence of any of the events itemized in (i) and (ii) above), the foregoing
indemnification is unavailable to NBI or insufficient to hold it harmless (other
than in accordance with the terms hereof), then the Indemnitor shall contribute
to the amount paid or payable by NBI as a result of such expense, loss, claim,
damage or liability in such proportion as is appropriate to reflect not only the
relative benefits received by the Indemnitor on the one hand and NBI on the
other hand but also the relative fault of the Indemnitor and NBI, as well as any
relevant equitable considerations provided that the Indemnitor shall in any
event contribute to the amount paid or payable by NBI as a result of such
expense, loss, claim, damage or liability any excess of such amount over the
amount of the fees received by NBI pursuant to the attached letter agreement.

The Indemnitor agrees that in case any legal proceeding shall be brought against
the Indemnitor and/or NBI or if governmental commission or regulatory authority
or any stock exchange or other entity having regulatory authority, either
domestic or foreign, shall investigate the Indemnitor and/or NBI and Personnel
of NBI shall be required to testify in connection therewith or shall be required
to respond to procedures designed to discover information regarding, in
connection with, or by reason of the performance of professional services
rendered by NBI and/or its Personnel in connection with the matters referred to
in the attached letter agreement, NBI shall have the right to employ their own
counsel in connection therewith, and the reasonable fees and expenses of such
counsel as well as the reasonable and out-of-pocket expenses incurred by its
Personnel in connection therewith shall be paid by the Indemnitor as they occur.

Promptly after receipt of notice of the commencement of any legal proceeding
against NBI or any of its Personnel or after receipt of notice of the
commencement of any investigation, which is based, directly or indirectly, upon
any matter in respect of which indemnification may be sought from the
Indemnitor, NBI and/or its Personnel will notify the Indemnitor in writing of
the commencement thereof and, throughout the course thereof, will provide copies
of all relevant documentation to the Indemnitor, will keep the Indemnitor
advised of the progress thereof and will discuss with the Indemnitor all
significant actions proposed unless precluded from doing so by law or court
order.

The indemnity and contribution obligations of the Indemnitor shall be in
addition to any liability which the Indemnitor may otherwise have, shall extend
upon the same terms and conditions to the Personnel of NBI and shall be binding
upon and enure to the benefit of any successors, assigns, heirs and personal
representatives of the Indemnitor, NBI and any of its Personnel of NBI. The
foregoing provisions shall survive the completion of professional services
rendered under the attached letter agreement or any termination of the
authorization given by the attached letter of agreement. This agreement shall be
governed and construed in accordance with the laws in force in the Province of
Ontario.

                                      -18-

         qualifications (collectively, the "Authorities") in all jurisdictions

         the Material Subsidiaries has received any notice of proceedings
         relating to the revocation or modification of any of the Authorities
         which, singly or in the aggregate, if the subject of an unfavorable
         decision, ruling or finding, would materially adversely affect the
         business, operations, financial condition, or income of GSC or the
         Material Subsidiaries (taken as a whole) or any notice of the
         revocation or cancellation of, or any intention to revoke or cancel,
         any of the mining claims, concessions or leases comprising:

                  (i) the Bogoso/Prestea property;

                  (ii) the Mampon property;

                  (iii) the Paul Isnard property;

                  (iv) the Prestea Underground property;

                  (v) the Yaou and Dorlin properties; and

                  (vi) the Wassa property.

         The properties specified in (i), (ii), (iv) and (vi) above are referred
         to, collectively, as the "Resource Properties" and each such property,
         other than the Mampon property, is as described in the Form 10-K of GSC
         dated February 3, 2004. The Resource Properties are material properties
         to the Company.

(k)      all interests in the Resource Properties and other material assets are
         owned, leased or held by GSC or its Material Subsidiaries as owner or
         lessee thereof, are so owned with good and marketable title or are so
         leased with good and valid title, are in good standing, are valid and
         enforceable, are free and clear of any liens, charges or encumbrances
         and no royalty is payable in respect of any of them, except as set out
         in the Offer Documents or as are not individually or in the aggregate
         material to GSC or Material Subsidiaries, or other than as would not
         have a material effect on the value of such interests; no other
         material property rights are necessary for the conduct or intended
         conduct of GSC's or the Material Subsidiaries' business and there are
         no restrictions on the ability of GSC or the Material Subsidiaries to
         use, transfer or otherwise exploit any such property rights, except as
         set out in the Offer Documents;

(l)      GSC and its Material Subsidiaries are in material compliance with all
         material terms and provisions of all contracts, agreements, indentures,
         leases, instruments and licenses material to the conduct of its
         business and all such contracts, agreements, indentures,

         leases, policies, instruments and licenses are valid and binding in
         accordance with their terms and in full force and effect;

(m)      to the best of GSC's knowledge, information and belief none of the real
         property (and the buildings constructed thereon) in which GSC or any of
         the Material Subsidiaries has a direct or indirect interest, whether
         leasehold or fee simple or otherwise (the "Real Property"), or upon or
         within which it has operations, is subject to any judicial or
         administrative proceeding alleging the violation of any federal,
         provincial, state or municipal environmental, health or safety statute
         or regulation, domestic or foreign, or is subject to any investigation
         concerning whether any remedial action is needed to respond to a
         release of any Hazardous Material (as defined below) into the
         environment. Except in material compliance with applicable
         environmental laws, neither GSC nor any Material Subsidiary nor, to
         GSC's knowledge, any occupier of the Real Property, has filed any
         notice under any federal, provincial, state or municipal law, domestic
         or foreign, indicating past or present treatment, storage or disposal
         of a Hazardous Material. Except in material compliance with applicable
         environmental laws, none of the Real Property has at any time been used
         by GSC or a Material Subsidiary or, to the best of GSC's knowledge,
         information and belief by any other occupier, as a waste storage or
         waste disposal site. Except as disclosed in the Offer Documents, GSC,
         on a consolidated basis, has no contingent liability of which it has
         knowledge in connection with any release of any Hazardous Material on
         or into the environment from any of the Real Property or operations
         thereon. Neither GSC nor any Material Subsidiary nor, to the best of
         GSC's knowledge, any occupier of the Real Property, generates,
         transports, treats, processes, stores or disposes of any waste on any
         of the Real Property in material contravention of applicable federal,
         provincial, state or municipal laws or regulations enacted for the
         protection of the natural environment (including, without limitation,
         ambient air, surface water, ground water, land surface or subsurface
         strata) or human health or wildlife. To GSC's knowledge, no underground
         storage tanks or surface impoundments containing a petroleum product or
         Hazardous Material are located on any of the Real Property in
         contravention of applicable federal, provincial, state or municipal
         laws or regulations, domestic or foreign, enacted for the protection of
         the natural environment (including, without limitation, ambient air,
         surface water, ground water, land surface or subsurface strata), human
         health or wildlife. For the purposes of this Section (n), "Hazardous
         Material" means any contaminant, chemical, pollutant, subject waste,
         hazardous waste, deleterious substance, industrial waste, toxic matter
         or any other substance that when released into the natural environment
         (including, without limitation, ambient air, surface water, ground
         water, land surface or subsurface strata) is likely to cause, at some
         immediate or future time, harm or degradation to the natural
         environment (including, without limitation, ambient air, surface water,
         ground water, land surface or subsurface strata) or risk to human
         health and, without restricting the generality of the foregoing,
         includes any contaminant, chemical, pollutant, subject waste,
         deleterious substance, industrial waste, toxic matter or hazardous
         waste as defined by applicable federal, provincial, state or municipal
         laws or regulations enacted for the protection of the natural
         environment (including, without limitation, ambient air, surface water,
         ground water, land surface or subsurface strata), or human health or
         wildlife;

(n)      except as disclosed in the Offer Documents, GSC and each of its
         Material Subsidiaries maintain appropriate insurance against loss of,
         or damage to, their assets for all insurable risks on a repair,
         reinstatement or replacement cost basis, and all of the policies in
         respect of such insurance coverage are in good standing in all respects
